The Suez Canal which connects the Mediterranean Sea with the Gulf of Suez on the Red Sea is a clear proof of the Earth’s and water’s non-convexity. The canal is 100 miles long and without any locks so the water within is an uninterrupted continuation of the Mediterranean Sea to the Red Sea. When it was constructed, the Earth’s supposed curvature was not taken into account, it was dug along a horizontal datum line 26 feet below sea-level, passing through several lakes from one sea to the other, with the datum line and the water’s surface running perfectly parallel over the 100 miles. The average level of the Mediterranean is 6 inches above the Red Sea, while the floodtides in the Red Sea rise 4 feet above the highest and drop 3 feet below the lowest in the Mediterranean, making the half-tide level of the Red Sea, the surface of the Mediterranean Sea, and the 100 miles of water in the canal, all a clear continuation of the same horizontal line! Were they instead the supposed curved line of globe-Earthers, the water in the center of the canal would be 1666 feet (502 x 8 inches = 1666 feet 8 inches) above the respective Seas on either side!

“The distance between the Red Sea at Suez and the Mediterranean Sea is 100 statute miles, the datum line of the Canal being 26 feet below the level of the Mediterranean, and is continued horizontally the whole way from sea to sea, there not being a single lock on the Canal, the surface of the water being parallel with the datum line. It is thus clear that there is no curvature or globularity for the whole hundred miles between the Mediterranean and the Red Sea; had there been, according to the Astronomic theory, the middle of the Canal would have been 1,666 feet higher than at either end, whereas the Canal is perfectly horizontal for the whole distance. The Great Canal of China, said to be 700 miles in length, was made without regard to any allowance for supposed curvature, as the Chinese believe the Earth to be a Stationary Plane. I may also add that no allowance was made for it in the North Sea Canal, or in the Manchester Ship Canal, both recently constructed, thus clearly proving that there is no globularity in Earth or Sea, so that the world cannot possibly be a Planet.” –David Wardlaw Scott, “Terra Firma” (134)
